5-124 MISCELLANEOUS CONTROLS AND OPTIONS
MTF0200
The low speed idling for first 1 minute forms
hydraulic pressure in the engine lubrication
system. Then, if increasing the idle speed for
3~4 minutes, engine oil can be distributed from
the oil pump sufficiently up to the individual
lubricating points of the turbo charger installed
considerably high above the other engine com-
ponents.
If the engine is accelerated with the lubricating
points of the turbo charger supplied insufficiently
with engine oil, intense heat generated by high
speed revolution(100,000 rpm) of the turbo
charger may cause burns to bearings and the
rotating part of the shaft.

(2) When parking the vehicle for prolonged time
If the engine is idled at low speed of 600~650
rpm for prolonged time, a sufficient amount of
oil cannot be distributed to the turbo charger,
resulting in premature wear of the rotating part
due to lack of lubrication. Therefore, when it is
unavoidable to park the vehicle for 30 minutes
or longer with the engine started, increase
engine idle speed to 900~1,000 rpm so that the
turbo charger can be supplied with a sufficient
amount of oil.
(3) After driving off
Avoid stopping the engine immediately after
driving off the vehicle. If the engine is stopped
immediately after the vehicle is driven off with
full load, the turbo charger fails to immediately
stop its revolution due to rotative inertia force
so that engine oil remaining on rotating part can
be completely burnt by the intense heat
generated from the turbo charger heated dur-
ing the operation of the vehicle, resulting in
damage to rotating part.
